DEGASSING SYSTEM OF RADON GAS INFILTRATING INTO INDOOR SPACE

摘要

PURPOSE: The degassing system of radon gas infiltrating into indoor space is provided to protect the indoor space of buildings from the radon gas which is harmful to human. CONSTITUTION: The degassing system of radon gas includes a porous inhaling pipe(13), a degassing pipe(12), and a degassing part. The porous inhaling pipe is buried under the ground(100) around a building. The degassing pipe is upwardly expanded from the upper side of the porous inhaling pipe. The degassing part is located at the upper side of the degassing pipe and reduces the pneumatic pressure of the porous inhaling pipe.
